Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Implementing Mesos and Marathon for BrownField microservices


In this section, the dockerized Brownfield microservices developed in Chapter 14, Containerizing Microservices with Docker, will be deployed into the AWS cloud, and we will manage them with Mesos and Marathon.

For demonstration purposes, we will cover only two services (search and website deployment) in this chapter. Also, we will use one EC2 instance for the sake of simplicity.

Installing Mesos, Marathon, and related components

Launch a t2.large EC2 instance with the Ubuntu 16.04 version AMI, which will be used for this deployment. In this example, we are using another instance to run RabbitMQ; however, this can be done on the same instance as well.

Perform the following steps to install Mesos and Marathon:

  • To install Mesos 1.2.0, follow the instructions documented in the following link. This will also install JDK 8:

https://mesos.apache.org/gettingstarted/.

  • To install Docker, perform the following steps:
sudo apt-get update
        sudo...
